Drought resistance and recovery ability are two important requisites for plant adaptation to drought environments. Proline (Pro) metabolism has been a major concern in plant drought tolerance. However, roles of Pro metabolism in plant recovery ability from severe drought stress are largely unexplored. Periploca sepium Bunge has gained increasing attention(More)
Periploca sepium Bunge is a native and widespread shrub on the Loess Plateau, an arid and semi-arid region in China. To understand the adaptability of its seed germination to dry environments, we investigated the germination rate, water relations, lipid peroxidation, antioxidant capacity and accumulation of major organic solutes during seed germination(More)
Chemical fruit thinning has become a popular practice in modern fruit orchards for achieving high quality fruits, reducing costs of hand thinning and promoting return bloom. However, most of the suggested chemical thinners are often concerned for their detrimental effects and environmental problems. 5-Aminolevulic acid (ALA) is a natural, nontoxic,(More)
5-Aminolevulinic acid (ALA), a newly proved natural plant growth regulator, is well known to improve plant photosynthesis under both normal and stressful conditions. However, its underlying mechanism remains largely unknown. Stomatal closure is one of the major limiting factors for photosynthesis and abscisic acid (ABA) is the most important hormone in(More)
It is an important task to provide the QoS-insured live media application in dealing with the fault effectively. The paper suggests a classification method to perform online fault management in the Live Media Service Grid (LMSN), which adopts online fault management, and can achieve low-overhead online learning, and adaptively adjust measurement sampling(More)
5-aminolevulinic acid (ALA), a new plant growth regulator, can inhibit stomatal closure by reducing H2O2 accumulation in guard cells. Flavonols are a main kind of flavonoids and have been proposed as H2O2 scavengers in guard cells. 5-aminolevulinic acid can significantly improve flavonoids accumulation in plants. However, whether ALA increases flavonols(More)
In this paper, we present a framework to facilitate Reputation-based service selection with reputation management, which has three key features. First, we use a structured overlay network as the decentralized service repository system for improved efficiency. Second, we propose an adaptive QoS-aware service discovery approach. Then, we present a(More)
Sour jujube (Zizyphus jujuba Mill. var. spinosus (Bge.) Hu) has gained considerable attention for its adaptation to drought prone environments. To characterize the physiological and biochemical basis of this drought adaptation, the effects of drought stress on Sour jujube seedlings were investigated in a greenhouse. Two contrasting populations were employed(More)
